To celebrate its 50th birthday, Venice's dive-bar, burger joint, and live band venue, Hinano, is holding a three-day food, drink, and music celebration starting today and ending on Sunday. Drink specials will rule the weekend, alongside live bands like The Venice Square Allstars, while tomorrow Hinano plans a free happy hour buffet. An employee tells us to expect a gratis spread of sandwiches and fixings like potato salad. 15 Washington Blvd. Venice.
